vided for the flow of water between the band i and the tiles to thejoint between the tiles.

A further object is to provide a device for holdingthe adjacent ends ofdrain tiles in alignment comprising a band of flexible material adaptedto overlap the joint between the tiles and provided with means on atleast the surface thereof which contacts against the surfaces of thetiles for permitting the flow of water between the band and the tileswhile holding the ends of such tiles in substantial alignment.

The above being among the objects of the present invention, the sameconsists in certain features of construction and combinations of partsto be hereinafter described with reference to the accompanying drawings,

and then claimed, having the above and other objects in view.

In the accompanying drawing which illustrates suitable embodiments ofthe present invention, and in which like numerals refer to like partsthroughout the several views,-

In the use of drain tiles it is a" frequent occurrence to find thattheadjacent ends of the tiles are out of alignment, thus havingpermitted earth to enter the interior :0f the tiles and plug the same.When such condition has occurred, it is invariably necessary to dig upthe tiles, clean them out and replace them, which operation entailsconsiderable time, labor and expense. Such misalignment invariablyoccurs when tiles are first laid or shortly thereafter on account of'theearth not being properly tamped whereby upon back-filling or consequentsettling of the earth the tiles move and get out oftheir respectivealigned positions. It also, often oc-. curs that the tiles are notfitted together properly when laid with'the'result that anabnormal spaceis left betweenthe same-through way and eventually plug the tiles. v i aBy the present invention we provide a device which eliminatesmisalignment'ofthe tiles and prevents the, earth from finding a freepassage through the joints betweenjthe same. As illustrative of thepresent invention we show in the accompanying drawing a pair of'tiles 15and 16 in axial alignment, and having their ends in substantiallyabutting relationship but spaced sufliciently fromieach other so thatthejoint 17 between the same affords a passage for waterfrom-theexterior to the interior of the tiles. Surrounding the ends ofthe tiles15 and 16 overthfe joint 17 in overlapping relationship respectthereto is a strip of material 18incorporati'ngthe present invention. I.7 1 f In the form shownin Figs. 1 to 5 ,'.inclu-.

sive, and in Fig. 8 theband' 18 is formed of a type of material similarto or thexsame as conventlonal roofing materlal having onesurfacethereof covered with crushed stone,

ice

. crushed slate, gravel or like material 19 as best shown in Fig. 3. Inthe form shown in Figs. 1 to 4 inclusive, the band 18 is of a lengthsubstantially equal tothe circumference of the tiles and 16 and isplaced about the same'over'the band 17 as indicated in Fig.1 with thesurface provided with the 1na-.

terial 19 in contactwith the surface of the tiles as indicated in Fig,2, the ends of the band 18 extending in-substantially contactingrelationship and. being secured together by a'clip 20. As indicated inFigs. 1 and' l,

I the clip 20 is formed from sheet metal and bent into a U-shape, theends of which are pointed, the bottom of; the U contacting aganst thesurfaceof thetiles and the pointed endsprojecting up through the free:ends of theband 18 as indicated bydottedlines I '1 in Fig. 4, and thatportion of the ends'which projects'through the band18 being bentrov'eras indicated. infu'll lines in Figs land 1 thereby securing the ends.of'theband [18 against separation. The material of the band 18 as sh'own in the above discussed figures is preferably of any conventionalroofing Inaterial provided'withthe material 19 on one side thereof, suchroofing material as a general r'ule'being made of acoarse grade. ofpaper treated with tar, asphalt or thelike, although it will be readilyunderstood that a strip of fabric or metal similarly treated and j'lOprovided with the material 19 on one surface thereof will equally servethe purposes of the present invention and is included therein. Suchmaterial asdescribed when'proper- 1y treated withtar, asphalt orsimilar-ma terial will withstand the deteriorating action v of the dampearth to which they are subject-: ed in the use as herein described fora period of from'15 to 30 years, depending upon the character of thesoil'and the amountofmoisture'in the same. 1 I 7 In placing the band18about the tileslo 5 and 16 in overlappingrelationshipto the A joint15, it will be apparent that the band '18 ineff'ect forms asleeve inwhich the adj acent ends of the tiles 15 and 16 are socketed,'thusholding the tiles'in alignment, and at the same I i time the-material 19disposed between the band 18andthe'adj acentsurfaces of the tiles 7provides a multitude of passageways through which the water in theearth-surrounding the tiles may'find its way to the joint 17 and ithence into the'interior of the tiles and' be 7 on a substantiallyfirmbed of earth'and'in' axial alignmentwithfeach other. A band carriedaway.

' In pract1ce,the method employed in using the bandsof the presentinvention is as'follows-:jWhen'" the trench isdug, the tiles are laidendto end within the same, care prefer- "6O ably being taken to have thesame positioned 18 is slipped over the j oint-17 between-each pair oftiles, the clip 20 ispla'ced between the free ends of the band and theends of the band 18 are then forced down over the ends of the clip, thusforcing theends of' the clip throughthe ends of the band, and the clipthat in the conventional manner of layingv tiles would give uponback-filling and allow the tiles .to become misalignechthe device of tthe present invention will hold such ends in o alignmentin spiterof suchfault of the bed below the tiles, and prevent lsuch'mis'alig'nment andconsequent entranceiof earthinto the tiles. Y

Although we have shownin Figs. 1, 2 r

3 a .particularmethod of securing ends of the band 18, in, position overthe jointj17 it will 7 be understood that the method shown is merelyillustrative of any suitable manner of securing such ends together, andother means for holding the band 18 in place such as-il-- lustrated inFigs. ,5 and 8, or any other means I may be employed. 7 In Fig. 5 asimple method; of securing the ends of the band together is shown. Inthat figure the band -18'is made slightly longer than the circumferenceof the:

tiles, the ends beingoverlapped when the band is in place and asplitrivetsuch as 21 is driven through the overlapping portions of the band,the ends of the rivets spreading when driven against the tiles andholding the In Fig. 8 the band band securely in place. is positionedover the joint 17 and one or more wires 22 is extended around the sameand twisted together thus holding theband 18 securely imposition. ,Othersimilar-means are readily suggested and maybe employed i when desired. 1

.In Figs. 6 and 7 amodifiedform of band is shown. In this modificationthe band. 23

-may be formed of the samematerial as-the band 18 but instead of beingprovided with the material 19 on one surface thereof, that surface isprovided'with a series of grooves or corrugations 24 which may bemolded, rolled". I

or otherwise formed in the one surface of the material to therebyprovide'iwater passages.

in the. same manner thatthermaterialil9forms 5 water passages for theband-18.. The jband'l 23 may be secured in place in the samfe'manner- I,as described in connection with the band .18, but wehave shownamodifiedmanner of securing the same in place comprising one or morewires25 which are preferably molded tudin ally of the same, the wires25projecting past the adjacent ends of theband andbeing twisted togetheras indicated" in' Fig. 7 to hold the-band in position.

Formal changes may" be made in the spe I or otherwiseformed within theband 18 lo'ngicific embodiment of the invention described withoutdeparting from the spirit. orsub:
